EPBCIPICATION forming part of Letters PatentNo. 337,522, dated March 9, 1886.

Application filed July 7, 1885. Serial No. 170,845. (No model.) Patented in France September 1-1, 1883, No. 157,547; in England June 16, 1884, No. 9,014; in Italy November 26, 1884, No. 17,450, and in Belgium December 15, 18:31, No. 67,016.

To aZZ whom it may concern.-

Be it known that I, Oscan SoHIMMEL, of Ohemnitz, in the Kingdom of Saxony and Empire ofGermany,haveinvented certain new and useful Improvements in Apparatus for Disinfecting Clothes, Textile Fabrics, Parcels, 820., (for which Letters Patents have been granted to me heretofore by the governments of Great Britain, 'NO. 9,014, dated June 16, 1884; France, No. 157,5l7,dated September 14,1883; Italy, No. 17,450, dated November 26, 1884; Belgium, No.67,016,dated December 15,1884,) of which the following is a specification.

Thisinvention has reference to an improved apparatus for disinfecting clothes, textile fabrics, parcels, bales, and other articles by means of steam and hot air; and the invention consists of an apparatus having a jacketed disinfecting chamber and an interior frame or cage in which the articles to be disinfected are placed and exposed to the action of hot air and steam, that are supplied thereto by a set ofheating-pipes and a live-steam pipe, the disinfecting apparatus being tightly closed and provided with a valved air induction pipe and a valved eduction pipe, as will more fully appear hereinafter, and finally be pointed out in the claims.

In the accompanying drawings, Figure 1 represents a vertical longitudinal section of my improved apparatus for disinfecting clothes and other articles. Fig. 2 is a horizontal section ofthe same on line a: :r, Fig. 1; and Figs. 3, 4, 5, and 6 are respectivelya vertical longitudinal section, a horizontalsection, a vertical transverse section, and an end elevation of another modification ot'the apparatus.

Similar letters of reference indicate corresponding parts.

Referring to Figs. 1 and 2 of the drawings, a a represent a circular wall of suitable nonconducting material. \Vithin the wall ais arranged a cylindrical disinfectingchamber, a, of boiler-iron, which is hermetically closed by a detachable lid, d, that ismade hollow and filled with sawdust or other suitable non-conducting material. The lid (Z is attached to the cylinder to by means of brackets and clamping-screws as. The lid (1 is suspended by chains passing over differential pulleys, which latter admit the convenient lifting of the lid.

To the under side of the lid (Z is attached a perforated cylinder or cage, h, having a perforated bottom and interiorcross-bars, r, with hooks r, for suspending the articles to be disinfected. Belowthe bottom of the perforated cylinder h is arranged a double set of steampipes, k k, which are connected with each other at the ends by bends, and with a steam-supply pipe, lc, having a stop-cockJc. The steampipes 7c are provided with a number of annular projecting ribs, by which a large heating-surface is obtained forheating the airin the cylinder a. The water of condensation is conducted from the pipes k by a pipe, 0, to a receiver, 0, having an overflow-pipe, c. The bottom of the cylinder a is provided with a pipe, 12, for draining off the water of condensation. A valve-casing, 0, at the lower part of the cylinder a, is provided with an adj ustable valve, 0, for admitting air to theinterior of the cylinder a. The upper end of the cylinder d is provided wit-h an eductiorrpipe, m, having a valve, m, through which the hot air is drawn off at the upper part of the apparatus. A perforated coil, Z, above the heating-pipes it it is connected by a pipe, Z, having a stop-cock, Z, with the steam-supply pipe in, and supplies live steam to the disinfecting chamber a. A thermometer, t, is located in the ednction-pipem, to indicate the temperature at the interior of the apparatus. The steam-pipes la la heat the air at the interior of the apparatus, while the live steam admitted through the perforated coil 1) acts with the hot air on the clothes or other articles in the chamber and thoroughly disinfects the same.

In Figs. 3, 4, 5, and 6 the disinfecting-chamher a is formed of a double-walled casing, the walls of which are filled with a suitable nonconductor of heat. The disinfectingchamber a is heated by a set of steam-pipes, ink, that are supported by rollers g on bottom rails, g, as shown in Figs. land 2, which are located at the lower part of the casing. The perforated steam-pipe Z supplieslive steam to the interior of the chamber a. A movable perforated bottom, h, is suspended by hangers h from a horizontal frame, if, which forms a cage with cross-bars'r and hooks r for the articles to be disinfected. The cage h h h moves by means of rollers g on top ails, 9 of the chamber a. The front wall of the disinfectingchamber a is provided with two doors, a" a, one below the other, of which the upper door, a serves for removing the cage h h h from the disinfecting-chamber, while the door a serves for lOlIlOVlllg the system of heatingpipes k is in case the entire apparatus is to be moved. At the lower part of the side walls of the chamber a are arranged valved openings 0 0 for the entrance of air when it is necessary to admit the same.

The douhlewalled casing is so constructed that the walls can be taken apart and put together again in order to facilitate the removal of the apparatus from place to place.

Havingthus described my invention, Iclaim as new and desire to seem re by Letters Patent-- In an apparatus for disinfecting, a removable cage or basket having perforated walls and bottom,a cross-bar provided with hooks,

my invention I have signed my name in preso ence of two subscri hing witnesses.
